The original title is "What Loop Engineering Needs From Runtime Infrastructure"

Short summary

Autonomous agent loops require production-grade infrastructure beyond prompt quality: isolated execution environments, granular tool permissions, persistent state across restarts, independent verification gates, and comprehensive observability. The engineering shift moves judgment into system design—runtime boundaries, tool policies, budget controls, and stop conditions. Without this infrastructure layer, a loop is merely an optimistic retry machine prone to token waste and uncontrolled execution.

• •Production loops need isolated runtimes, tool policies, and persistent state—not just good prompts
• •Independent verification (tests, CI, human review) is more important than the executor agent itself
• •Observability and explicit stop conditions prevent runaway costs and maintain audit trails
